Flow Mechanism in a Pipe Fitting : Part 5-Flow Mechanism in a Pipe Fitting with Branching Angle of 135-deg. in Laminar Flow

Abstract

It is very important for industry to clarify the shape of a pipe fitting with the branching angle of 135° which has small energy loss caused by flow dividing in turbulent flow. In this paper, before the shape is investigated, the results are reported which were obtained by the theoretical analyses and experiments in the laminar flow for the pipe fitting with sharp edged lateral entrance which is the most fundamental shape.
